My wife's real sister who came to help me with housework because my wife was hospitalized. Tsubaki-san, who is her husband's sister-in-law, is beautiful, good-natured and takes good care of her, so she does everything for her brother-in-law. She becomes intimate with her life alone... Even though her sister-in-law is a married woman with a husband, she has a dense fornication with her sister-in-law while her daughter-in-law is away! Drowning in forbidden pleasures that should never be revealed!
